Method for allocating resource for signal by terminal in wireless communication system and apparatus therefor

Abstract

The present invention relates to a method and an apparatus for allocating a resource by a terminal in a wireless communication system supporting carrier aggregation. Specifically, the method comprises the steps of: receiving a configuration of a resource pool for signal transmission; and allocating at least one message to at least one resource unit on the basis of the resource pool, wherein the allocated resource unit is selected on the basis of the transmission capability of a terminal. The terminal is capable of communicating with at least one of another UE, a UE related to an autonomous driving vehicle, a base station or a network.

The invention claimed is: 
     
       1. A method for allocating resources by a first terminal in a wireless communication system supporting carrier aggregation, the method comprising:
 receiving a configuration of a resource pool for signal transmission; 
 based on a sum of powers of N messages not exceeding a power limits of UE, transmitting the N messages to a second terminal through different N carriers in a first subframe based on the resource pool; and 
 based on the sum of the powers of the N messages exceeding a power limits of UE, transmitting M messages to the second terminal through different M carriers in the first subframe based on the resource pool, and N-M messages to the second terminal through different N-M carriers in a second subframe different from the first subframe, 
 wherein the M messages are selected as a message combination that comprises the majority of the N messages, and 
 wherein each of the N and the M is a natural number, and the M is smaller than the N. 
 
     
     
       2. The method of  claim 1 , wherein resources for the N messages are selected based on a ProSe per-packet-priority (PPPP) or a channel busy ratio (CBR). 
     
     
       3. The method of  claim 1 , wherein resources for the N messages are configured differently according to the N carriers. 
     
     
       4. A first terminal for allocating resources in a wireless communication system supporting carrier aggregation, the first terminal comprising:
 a transmitter and a receiver; and 
 a processor configured to: 
 receive a configuration of a resource pool for signal transmission; 
 based on a sum of powers of N messages not exceeding a power limits of UE, transmit the N messages to a second terminal through different N carriers in a first subframe based on the resource pool; and 
 based on the sum of the powers of the N messages exceeding a power limits of UE, transmit M messages to the second terminal through different M carriers in the first subframe based on the resource pool, and N-M messages to the second terminal through different N-M carriers in a second subframe different from the first subframe, 
 wherein the M messages are selected as a message combination that comprises the majority of the N messages, and 
 wherein each of the N and the M is a natural number, and the M is smaller than the N. 
 
     
     
       5. The terminal of  claim 4 , wherein resources for the N messages are selected based on a ProSe per-packet-priority (PPPP) or a channel busy ratio (CBR). 
     
     
       6. The terminal of  claim 4 , wherein resources for the N messages are configured differently according to the N carriers.
